Start an FTP or SFTP Server in Mac OS X

If you’ve visited the Sharing Preference panel in the newer versions of Mac OS X you may have noticed there is no longer the direct option to enable an FTP server to share files and folders. Well, at least there isn’t an obvious option, but the FTP and SFTP server function does still exist, the two have just been split into different functionalities, with the new versions of OS X preferring SFTP rather than FTP. Regardless of what you want to use, setting up a server for either of them is extremely simple, and we’ll walk through how to start either an FTP or SFTP server in OS X.

Each of these FTP/SFTP server tricks work in all new versions of OS X, be it OS X Yosemite 10.10.x, Mavericks 10.9, Mountain Lion 10.8, or 10.7 Lion.

Start the FTP Server in OS X

This will start a generic FTP and FTPS server on the Mac, but not an SFTP server:

Launch the Terminal (/Applications/Utilities) and enter the following command to start the FTP server:

You know the server is running. If you don’t see that, then the server either hasn’t finished starting yet or you didn’t enter the command properly. You can then FTP from other Macs via the same ftp command, or by using the “Connect to Server” option in the Finder.

Enabling the SFTP Server in OS X

As you probably know, FTP is unencrypted and as a result as fallen out of favor for security reasons. Enabling SFTP is actually easier than FTP on the Mac these days:

Disable FTP or SFTP Server in OS X

As the command suggests, this unloads the ftp daemon and shuts down the server. Obviously you can only shut down and disable the FTP server if it was enabled to begin with.

Disabling SFTP is just a matter of unchecking the “Remote Login” box that sits within the Sharing Preference Panel of OS X.

If you’re wondering how any of this is different from prior versions of OS X, you would have to look to Snow Leopard (10.6) or before to find the difference. Previously, an FTP Server option was a toggle within the general sharing preference panels like this:

Though it’s not entirely clear why Apple pulled the easy frontend to FTP sharing, it’s possible they are simply choosing to favor SFTP because it’s a more secure protocol, and by enabling one you enable both. Nonetheless, FTP and FTPS servers are still around (as are clients for that matter), so it’s simply a matter of using the terminal to enable the server side of things. Generally speaking, because SFTP is much more secure, that is what you should be using for remote file transfers and connections though, so keep that in mind if you plan on hosting any kind of server to the outside world, or even if you just want to have secured file transfers yourself to and from remote Macs.

This is an elaboration on a tip from Land of Daniel via TUAW, who goes on to explain how to get ftpd to launch automatically on reboot, so if you’re interested in that, don’t miss their post.

The reason this was removed is that Apple is slowly simplifying OS X so that when it merges with iOS there will be no options to run servers or share files, any sharing will be done through iCloud and within apps.

Forgive my ignorance but I have an iMac that, after installing Lion and restarting, I cannot log in to. I can still boot into single user mode. Safe mode does not work. I tried creating a new account via the deletion of the startup file and went through all of that and it still does not work. I can access the files on the iMac from my MBP because FileSharing is enabled. Unfortunately I did not enable Remote Login on the iMac before I had the problem. Since I can boot into the root account via SUM, I assume that I could turn on Remote Login if I knew what to do. I have tried /sbin/service ssh start while in SUM but when I restarted I have been unable to ssh into the system which tells me that login is refused or words something like that. Any ideas? Thanks.
